Spent the last couple of days trying to come to grips with the new system and tune it somewhat. Apart from the GZ amp, everything in the setup is new, and hence will take me some time to understand their nuances.
The Clarion HU, in particular, has lots of features which I have never used before - for example, Time Alignment. The user interface on the HU is also very different from the Alpines and Pioneers that I am used to. So, taking a little time to explore all its features, and for the first time I actually read the user manual
Shuvc helped me tune the system initially and Xeta dropped by today to add his inputs. Currently, it is sounding very nice, but I still have some fine-tuning to do. Will probably have to increase the gains on the Carbons slightly and reduce the sub gain a bit. Time to experiment and let my ears decide...!
The Carbons are quite something. Amazing clarity, brilliant sound reproduction. I don't have the technical know-how to put it down very scientifically, but in plain English, they sound awesome! I am hearing minor details in some tracks that I have never heard before. No exaggerations. Definitely a big step-up from the Electras, which, in their own right are great speakers. Are they 5 times better, going by their pricing? No clue - all I know is that they sound heavenly!
Need to tune the mono+ GZ Radioactive sub a bit more, but the combo sounds very promising. Plays low, plays fast, plays crisp. No boominess and gels well with the Carbons.
Time alignment is something I was looking forward to, but it takes some getting used to. After so many years of listening to setups without TA, the TA-wala system seems different. You get kinda confused initially - Why is the sub sound coming from the A/C vents? Why is the sound concentrated around me, and not playing all over? Takes a little getting used to, but it's very, very worth it!
The additional damping (around 50 sq.ft of it in total now) has made a huge difference. Not a vibration or rattle to be felt, even at the loudest of volumes. Cabin feels super enclosed!
End of the day, I am happy. I spent a fair bit on this upgrade, but I think it was worth it. I love cars, I love music, and I spend a fair amount of time in the driving seat. A good audio setup in my car makes sense
My sincere thanks to all those who helped me in this quest of mine, directly and indirectly. Ajay, kumar_ranjan, Karan (Ace6120), Xeta, shuv c, me_sid, vro(7)m, hydrashok, abhinav, frank, LBM... the list is long, and I am sure I left out some names. Thanks guys.
